I'll ask Veriz to stop by here as I'm not sure about your call pre with QQ. Maybe the best would be to 3bet yourself and avoid people behind you having odds to call too much or even squeezing like that.

Once he 3bets I think it's an easy call with QQ. Considering his stats, his stack and the limit I'd say his range is super wide there. He might be shoving many pockets, but I'd say at the very least TT+, and aces maybe even like AJ+ or AT+.

Was he a *very* tight player you could consider folding, but since he's shoving wide and is showing to be a bit of a maniac I consider this to be a clear call.

If you have such an opponent behind you who even ships so loosely I don't mind flatting and letting him ship with worse crap.
Against UTG range we anyways have to 3bet/Fold very often. But usually if there wouldn't be such an opponent then you could as well consider 3betting it preflop.
